I have myself a poetical enthusiasm for pigs, and the paradise of my fancy is one where pigs have wings. But it is only men, especially wise men, who discuss whether pigs can fly; we have no particular proof that pigs ever discuss it.
Suppose one who had always continued blind be told by his guide that after he has advanced so many steps he shall come to the brink of a precipice, or be stopped by a wall; must not this to him seem very admirable and surprising? He cannot conceive how it is possible for mortals to frame such predictions as these, which to him would seem as strange and unaccountable as prophesy doth to others. Even they who are blessed with the visive faculty may (though familiarity make it less observed) find therein sufficient cause of admiration.
